Z87 and an i7 is not optimal for a fanless setup, but it is doable. With very high temps I would be concerned about the longevity of the hardware inside the case, not primarily the CPU. The CPU will throttle down if overheated and how high temps one is willing to accept are really a matter of personal preference. 92C is way to hot imo and I would look into underclocking and undervolting if I were you. Should be possible with that motherboard.

Thanks for your reply. So what exactly would be breaking if not the CPU, the MoBo?

I struggle to see how Prime95 is any sort of real world test, and idle temps for what I will be doing on this (watching movies, surfing, MS Office, emulation of 16 bit games etc) seem to be fine? I ran it because everyone runs it but this is no gaming PC.

Sorry just a follow up as I see from your signature you have a lot of experience with fanless/no moving parts build.

Do you think with that Mobo and CPU combo those temps seem normal for Prime95 or would there be any benefit to take it apart and reapply the thermal paste? I woudl say I did an OK job but could do a better job if I tried again.

Personally I dont know as much as you guys but I dont see any problems with idle/medium use at 40-50C.

what others have said,+ its all going to depend on airflow and ambient temps around the case, what your real usage will be, and how many monitors/at what res. Sticking it in an enclosed, unventilated AV rack, or behind a hot TV will be very problematic. (I assume no folding/mining ect.)

also might want to get low volt ram, if you haven't yet.

EDIT;

Oh, and, WELCOME TO SPCR!!!

Thanks, the RAM is regular Corsair Vengance low pro, I shoudl have gotten the low volt but I didnt I will build a dedicated Windows based server in a couple months so I may have to wait until then and switch out the RAM at that time.

THe location is a very open location, its not boxed in at all, completely open.

Usage is browsing the web, Using MS Office (emails etc) reading comics, organizing comics, organizing and playing music, organizing and playing movies (XBMC). Light gaming which is basically old emulated NES/SNES games, no modern gaming. Just 1 monitor (for now). 1080p.

If you don't see CPU temps above 60C for your apps, don't worry about it. Prime95 is an unreasonable stress test compared to the applications you listed. You should monitor the other temps available to see if anything is baking long term. OCCT is a decent tool to expose the voltages/temps. Or Speedfan.

I really appreciate all the help! SPCR is a great recourse and I will definitely make a post when I am about to start building by Windows based NAS server to check my parts list.

I think what I will do regarding this build is leave everything as it is for now, keep monitoring temps to see if they ever creep into the 60s and why. I am going to buy a WD Red 3TB drive next month and put it in this case. I know I know, it wont be a "no moving parts" build after that, but its only temporary. Eventually that drive will come out and go into my NAS.

When I install the WD Red I am going to take apart the heatsink and copper pipes and reapply thermal paste (man that is going to be a shit job to clean up the old paste). Then I will test the temps again. If the temps dont improve after that I will probably replace the 4770S 65W processor with a 4770T 35W processor OR undervolt/underclock the 4770S. Which do you think would be the better option? I dont have any experience with overclocking/underclocking so I am a bit nervous about that, but I would prefer to keep the CPU speed as fast as possible.

Now that you have an i7 4770S, there's no reason not to use it. But I think a dual core like an i3 or even a Pentium would fit better in that setup, especially considering the cost of an i7. A quad with hyper threading gives you plenty of power for stuff that can be parallelized. But if the heat forces you to underclock it a lot, then single thread performance will suffer. It will handle the stuff that you mention though, with ease. All at the same time if needed.

SIGH, ya I am seeing your point. I am leaning to changing this CPU out for an I3 35W 4330T @ 3.0. I guess Ill just sell my i7 after that.

Last question, is it worth it to try to reapply the thermal paste? I used 2 full tubes of arctic silver but I dont think I "filled teh cracks" where the pipes attach into the case. I definately covered all the flat surfaces but there are spaces next to the round pipes I could have done a better job to fill that with thermal paste.

Note the ATX extension and the internal USB 3.0 extension. I knew from reading online that those would be problematic with this case as the heatpipes get in the way. However it ended up working nicely.

Nice pics, thank you. I used the first FC-8 in my previous build. There's some improvements in the new version.

If you think you need more paste, I would add more paste. But no need to clean the old stuff off from the pipes and begin from scratch imo. You could also first try to determine if the contact between the pipes and the case side is good or not. Temps are very high with the i7 at stock settings, but you could try disabling two cores and make it a dual core, if you have such an BIOS setting. If Prime95 temps are acceptable with two cores and the case get warm/hot as it's supposed to, then thermal contact is good.

The heatpipes are tricky, difficult to know how much paste is optimal. I usually use more than optimal I think, but I use the cheaper Arctic Silver Ceramique compound. Comes in huge 22g syringes.

No need to get a T version of the i3 btw. That case can handle a normal TDP 55W dual core.

Cool thanks, I guess I will play around with it a bit more, temps dont run above 58/59 when playing 1080p, watching youtube, downloading torrents, and browsing the web watching gifs etc, all at the same time. Usually its closer to 55 degrees.

Can you explain to a noob what exactly does disabling cores do? I mean does it slow down the CPU? Sorry for being so dumb. When I ordered the parts I read online that you could do 65W so I just got the fastest/best 65W CPU there was.

When running prime95 the case and fins definately get hot and they are warm at idle or browsing so I know heat is being transfered, I guess the question is just how much and is it enough.

I'm no expert, but I've found an option in the BIOS/UEFI settings on many boards that lets the user set the number of active CPU cores. I've never played with that setting myself, but I assume that it means you can in effect turn a quad core into a dual core. The Steacom FC8 can handle the heat from two cores, and if you still would experience unusually high temperatures that might indicate poor thermal contact.

I first tried an i5 in my Steacom FC8 btw, and then stepped down to an i3.

The heatpipes are tricky, difficult to know how much paste is optimal. I usually use more than optimal I think, but I use the cheaper Arctic Silver Ceramique compound. Comes in huge 22g syringes.

IME the supposed quality of the thermal paste won't do any practical difference: however, it's true that AS5 has a long curing time, I'd expect the OP should gain 3-5°C after the canonical ~200 hours for break-in.
